eraro

Create JavaScript Error objects with code strings, context details, and uncluttered stacktraces

For use in library modules to generate contextual errors. Your library module can return an error code for programmatic inspection by calling code, and error details as a context object for custom messages and fault inspection.

Stack trace lines referring to eraro itself, and your library, are removed. This means that the first line of the stack trace refers to the position in user code where your library was called.

var error = require('eraro')()

throw error('code_string')

// provide a user message
throw error('code_string', 'Message text.')

// supply context details for error
throw error('code_string', 'Message text.', {foo:1, bar:2})

throw error('code_string', {foo:1, bar:2})

The Error object has the following additional properties:

• code: code string
• details: context details object
